https://devzone.nordicsemi.com/f/nordic-q-a/120362/pkk2-measurement-difference-between-ampere-mode-source-modeHello, I use a PKK2 for power measurements on a nRF9160DK and Feather nRF9160 from circuit dojo. With the UDP example to test it out the sleep current so I can determine if a battery powered device is possible. When using the DK as in the exampleen-USTelligent Community 13Tue, 01 Apr 2025 16:03:52 GMThttps://devzone.nordicsemi.com/thread/530054?ContentTypeID=1Tue, 01 Apr 2025 16:03:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ea4b363d-a0ee-4cb9-97e7-43484c131009Achim Kraus<p>You measure the &quot;complete DK (including the jlink + USB)&quot; instead of only the nRF9160 via P22/VDD nRF.</p> <p>And also in the case of the feather, you power the USB.
